Figure 6 is a transverse section taken on line G--G of *Figure 5.

My device comprises a base-1', poleat- X-shape in cross section, the

1 ispreferably 'the full'length of the Abase ribs 4y extending l and'yflaring outwardly atV their lowenpor-f tions and there provided withflanges, the opposing faces ribs are parallel and grooved at 6to receiveof the lower portion of the base. ,v

The upper portion of basel is provided with a flat face 7 and is alsoprovided with transverse passages 8 which areV preferably arranged atright angles toeach other and extend clear through the base laterally.The pole attaching members 2 are L-shaped and their horizontal legs areadapted to slidingly fit vslots 8 so that the members may be in? iserted in the slots and moved transverselyy The horizontal legs eachcom-y of the base.

prise a vertical web 25 4which fits intoa vertically formed portion ofthe passage.

Laterally on each side of the vertical web .25 is formed an outstandingshelf-like por- Ation portions ofthe passage 8. Hence the. horizontal'legs cannot be twistedv from their original positions within thepassages 8 and the vertical legs of member 2 are held upright. Thevertical legs of member 2 are the pole vbutt in' the` ground more firmlythan could be doneby 5 of v.which ontwo adjacent.

By 'means of the bolts and -their nuts, the

poleis clamped between the members andv` .to

the base. v

Theupper'end of'each member 2 is pro-k vided with a projecting lug 11adapted-to serve as a fulcrum to engage the end fot a-erowbar or similar'lever inserted between the lug and the ad]acent bolt Ahead orwnutwhich-maybe manipulated to forcethe pole downwardly jagainst face A7y oftheifba'se. The outer `faces of members '2 are corrugated .as shown at12 to more firmly seatthejwashers provided near the boltlvheadsandj'n'uts.`

An additional securing element is shownl in Figures 1 andQ and..consists-i'na strap passed around the attaching members `and pole withits ends 14 overlapping andexf' tending throughV a' block 15againstdwhich the pole'inv position.. In usi-ng my device,4 the ybutt`base canbe insertedvin the ground'to any desireddepth depending upon the'exact y cutting-off point of the pole.- The pole may. then beswung;laterally over-thebutt and and bolted in position.,l f f lbearnuts 16 by which the ends'ot the strap may bejdiawnin oppositedirections to clamp y so It willnot ordinarily necessarytoiiusel 4band13 and'bolts 10 simultaneously-- .One or thefother may beeliminated, although the presence of .both afford double security.

In the modification shown'in Figure '4,

. ribs 4 are not enlarged ,to provideopposing .grooves inadjacentlribsbut the base between the ribs is increasedin cross sectionalarea and is curved outwardly and provided with -Tslotsfadapted toreceive the T-head `like 'f lproject-ions 17 formed on'flukes 18. y

VVVh'le Figures 3 and 4 eachv show four flukes it will be understoodthat two of these may be eliminated without Vmateriallyaffecting theresistance: of the base'. :against lateral stresses appliedrin thedirection which these flukes extend. In` other wordsyby pro-v 'vidingthese flukes `iii directions at right angles to the lines .carried bythepole, all of thenecessary 'biaciiigwvill vbe secured.

Another modification ofmy invention isvr illustrated in Figures 5 and 6in lwhich the pole holding members -19 are straight bars 1 and aresecured to the base -by bolts "ZO instead of being L-sliaped andinserted in slots roe lio

in the base. This provides a less expensivef Vthen the 4members 2.inserted in their slots .H5 f

construction and for many installations Will be suiiiciently rigid toobtain the desired results. f

c In this construction, the lukes 2l are provided With T-headprojections 22 similar to the flukes shown in Figure 4 but the slots 23for these flukes are provided on the enlarged outer portions of theribs. This construction requires a minimum amount of ma- Vtioning thepole relative to the base.

2. In a. pole butt, a. base, slotted members on said basefor gripping apole'and means associatedwith said members for clamping the end of saidpole against the end of said base.

3. Ina pole butt, a base, spaced members extending above the base andadapted to slide across said base, and vertically adjustable elementsconnecting said members for clamping a pole between them. Y

4f., In a pole butt, a base having transverse slots, L-shaped members,the horizontal legs of which are longitudinally and slidably positionedin said slots,'and the vertical legs of Which project above said'base,and means for securino' said members against movement u s C 1n saidslots.

5. In a pole butt, a base having transverse slots, LV-shaped members,the horizontal legs of which are slidable in said slots and adapted tobe extended beyond' the rlimits of the base and the verticallegs ofwhich projectabove said base, and bolts extending longitudinally throughlopposite members at verse slot, an L-shaped member, the horizontal legot' which is slidable in said slot and' the vertical leg of whichextends Vabove said base, a slot'in the vertical leg of said member, abolt inserted through said member slot, and a projection upon thevertical leg of said member, adapted to serve as a fulcrum for a leverengaging said bolt.

7. In a pole butt, a base having transverse slots, L-shaped members, thehorizontal legs of which are slidable in said slots `and the verticallegs of which project vabove said base and are slotted, and verticallyspaced bolts extending through the slots of the opposite members.

8. In a pole butt, a base of X-shaped cross section, forming verticalribs, the upper end of Which base is flat and provided With transverseslotted recesses formed in the ivertical ribs at right angles to eachother, members slidable into said recesses and having upwardly extendingportions adapted to engage the sides of a pole, andmeans for clampingsaid membersto the pole. j

9. In a pole butt, a base,'slotted Vpole engaging members mounted onsaid base and extending above the same, a pole securing bolt resident inthe slots and extending through said members, said members beingprovided With outwardl projections above said bolt adapted to serve asfulcrums for a lever engaging said bolts.

ll0. In apole butt, a base having a slot, a clamping member having aportion slidf ably positioned in said slot and adapted to extend beyondvthe base'and a Yportion ex tending above the base, and means for spaceadjustment between the pole and base.
